a lighter bulb
A while back, gg explained Earnhsaw’s theorem and the application to magnetic levitation; you can’t trap a dipole with static fields. But that’s OK, because you want a time-varying field so that you can transfer the energy via induction. The bulb is modified to do this.

Atmospheric pressure is about 10 N/cm^2, but there are a whole lot of square centimeters on that tanker — the more familiar unit is N/m^2 (Pascals), where 1 atmosphere is 101325 Pa (or possibly even more familiar 14.7 psi).
Various sites showing this have claims [...]

Light Pillars
Typically seen in polar regions, the vertical columns of light have been appearing along with frigid temperatures at lower latitudes this winter.
Light pillars appear when artificial light or natural light bounces off the facets of flat ice crystals wafting relatively close to the ground.

Light Transmitting Concrete
Litracon is a combination of optical fibers and concrete. A wall made of Litracon has the strength of traditional concrete but thanks to an embedded array of optical glass fibers, which lets in the view of the outside world, such as the silhouette of trees, or passersby, that are displayed inside the building.
